Cause of sin according to your scriptures
The human body created in the image of God is the jewel of His creation. All human being have higher intellect and power of discrimination. Every human body has a soul. Soul is different from body as fire is different from wood. God made all things with His cosmic energy.
The ignorant is not able to make distinction between soul and body. The same Lord exists equally in everything. Creation is projection of divine power of God. Everything is connected with each other. Creation is the divine splendour of God. Creation is governed by illusion or cosmic power of God. Intellect, mind, wisdom and power of discrimination govern the body. There are five senses i.e. hearing, touch, sight, taste and smell; the five sense organs – ear, skin, eye, tongue and nose. Supreme intellect controls the function of these organs. The mind and matter are both energy according to Einstein.
There are three types of attributes in body. Supreme intellect controls these attributes based on the force of energy of one attribute. Real nature of divinity of human being is forgotten. One attribute is Satva, being pure, illuminating and good. Second attributes is Rajas or passion is characterized by intense (selfish) craving. It is source of desire and attachment. It binds with the fruit of work. Third attribute is Tamas or ignorance. It is negligence, laziness, lustful, aggressive, possession by violence, greed, inactivity etc. These lead to committing sin. He feels that he is the doer. He does not have faith and love in God. In ignorance, he commits all sins.
